The Shop Fox at this time is not looking good for me. I want a 4-jaw, faceplate, and compound rest which are all extra costs with the Fox. And it is just barely big enough to do some things I would like to do today, so no extra margin for bigger things tomorrow. I would say its probably as good as most of the other mini-lathes, but I need to think larger. But, it's always the matter of keeping the costs down, sadly.
The Grizzly G0768 and G0602 look more promising. The 8x16 has the advantage of being light enough to mount on any sturdy work table/bench. The 10x22 would probably need its own bench/stand at its weight, but it has numerous advantages over its little brother, including a feed rate down to 0.0025"/rev. And both are nicely equipped.
I would be machining mostly aluminum, plastic, and wood, and occasionally steel and SS. Anyway I won't being buying anything until probably spring, so I have plenty of time for research and evaluation of the options.
